3D-printed microreactors ; Characterisation of hydrodynamic conditions in microreactor manufactured by PolyJet Matrix Technology

Hydrodynamic characterisation of microreactor sistems is importan for the microreactors application and construction improvement and it can be used for the prediction of system behaviour. Pressure drop, Reynolds number was determined in the wide range of process conditions (residence time 3-40 s, the flow rates 0.2-1.5 ml/min and microreactor length 1-100 cm). Pressure drop increase with the microreactor channel length and flow rates incensement and it was in the ranging between 25.50 and 142.16 kPa m-1. Significant changes of pressure were observed in the last section of microreactor. Reynolds number was in the range of 7-127. Hydrodynamic condition was characterised by dispersion model. The obtain Bodenstain numbers were in the range of 100-600. Using simple criteria for microchanels hydrodynamic characterisation and given results plug-flow conditions with the relatively small axial dispersion determine hydrodynamic properties in the constructed microreactor. This characteristics can be used for the appropriate microreactor application and enhancement of microreactor performance.
